1. Introduction. Gold recovery is often well below copper recovery in copper–gold flotation plants Zheng et al. 2010 .As liberated and copper-associated gold is readily recovered by flotation this recovery difference is often due to operating strategies that require rejection of gold-bearing iron sulphide gangue in order to maintain a saleable copper concentrate grade.
grade copper-gold ores from open pit and underground sources in two parallel processing trains. The copper flotation circuits upgrade copper content by a factor of 80-160 times from feed to a saleable copper concentrate containing approximately 50% of the contained gold in feed remaining gold is recovered
I have been given a project on optimization of copper concentrate grade so as to improve copper and gold recovery. I need help on the main factors which I have to consider in my project. The targeted copper concentrate grade at the plant is 18- 20%Cu but currently the target is not achieved. The p
The flotation method is a widely used technique for the recovery of gold from gold-containing copper ores base metal ores copper-nickel ores platinum group ores and many other ores where other
cording to ore type i.e. gold ore gold copper ore gold antimony ores because the Sotation methods used for the recovery of gold from different ores is vastly different. Geology and General Mineralogy of Gold-bearing Ores The geology of the deposit and the mineralogy of the ore play a decisive role in the selection of the best treatment
The flotation of gold-bearing ores is classified according to ore type i.e. gold ore gold copper ore gold antimony ores etc. because the flotation methods used for the recovery of gold from different ores is vastly different. 17.2 GEOLOGY AND GENERAL MINERALOGY OF GOLD-BEARING ORES
